A filling that is made from composite resin can do an effective job of restoring your tooth after a cavity. It has the ability to look like your own natural enamel, and it is capable of bonding with your tooth. You may have an older filling that is not made from this material. In the past, dentists would restore a tooth with metal. These metal fillings, which were also referred to as silver fillings, or amalgam fillings, can have a more conspicuous appearance. They also have functional disadvantages compared to composite resin. If you have a problem with an existing metal filling, or would like to have improved support, it is possible for your dentist to replace a metal filling with composite resin.
Why Replace A Metal Filling With Composite Resin?
If your metal filling has become worn or damaged, it may be due for a replacement. You could also switch to composite resin for the cosmetic benefits. It is worth noting that metal fillings can become loose; unlike resin, metal fillings are not able to be bonded directly to your tooth. You could also experience discomfort due to a metal filling’s tendency to expand or constrict when placed under temperature extremes.
Other Uses For Composite Resin
Composite resin’s capacity for mimicking the appearance of your enamel does grant it a cosmetic function. Dental bonding involves the application of this material to your tooth, for the sake of improving how it looks. You could make a tooth look larger, to cover a gap. You can also hide evidence of a past injury by taking care of a small chip or crack.
